![]() ![]() In this type of splicing, an elastic tube is used to form a connection between the two optical fiber cables. It is very easy to repair and install for both multimode and single-mode optical fiber cables. But it produces high back reflection when compared to fusion splicing. That means insertion loss, splicing loss will be nearly 0.3dB. When the optical fiber cables are joined together to pass the light from one to another, the loss of light will be low if we use the mechanical splicing technique. The mechanical splicing acts as a junction to join the optical cables more precisely. It uses index matching fluid to hold and align the single or more fiber cables assembled in a place to join them together. This technique doesn’t require a fusion splicer to join the optical fiber together. The disadvantage of fusion splicing is, if excess heat is generated to melt the fiber cable for joining, then the join would be delicate and can’t be used for a longer run.The insertion losses (<0.1dB) are less in both multimode and single-mode optical fiber splicing. This method has less attention loss of 0.1dB, and also black reflection loss is low.It helps to create an electric arc or heat to fuse or join or weld the optical fibers together. ![]() It helps to align the optical fibers with more precision.The functions of the fusion splicer used in the splicing of optical fiber are, So, it is most widely used and expensive than mechanical splicing of optical fiber cable. The light loss will be low in this technique. The heat produced by the electric arc can give a transparent and continuous non-reflective connection between the two optical fiber cables with less attention, and insertion losses. So, those cables can be fused or joined together to form a connection with the help of an electric arc more precisely. In this method, the two fiber cables are aligned together by using a device called a fusion splicer. The schematic diagram of the fusion splicing of optical fiber technology is shown below. This technique is very costly and works for a longer period. That means an electric device or an electrical arc is used to fuse the two fiber optic cables and produces a connection between them. The two cores of fiber cables are joined or fused electrically or thermally. This technique of splicing gives the permanent connection between the two optical fiber cables and gives a longer life with less attenuation. The two optical fiber cables should be aligned properly while splicing and at the same time its geometrical factors and the mechanical strength should be considered. The mechanical splicing is again divided into two types such as V-grooved splicing and elastic-tube splicing. They are fusion splicing and mechanical splicing. There are two techniques in splicing of optical fibers depending on the insertion loss, cost, and performance characteristics.
